WATCHCASE-HINGE.

Specification of Letters Patent.

Patented Oct. 24, 1905.

Application filed April 11, 1905. Serial No. 254,958.

To Ml whom, it may concern:

Be itknown that I, LoUIs S. HANSON, a citizen of the United States, residing at Huron, in the county of Chippewa and State of Wisconsin, have invented certain new and useful Improvements in WVatchcase-Hinges; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to watchcase-hinges, and has for its object the construction of a case having a lid with an improved hinge and means for opening said lid.

It consists of the constructions, combinations, and arrangements of parts hereinafter described and claimed.

In the drawings, Figure 1 is a bottom end View of said case, partly broken away, showing said hinge; and Fig. 2 is a vertical section of the lower portion of said case on the line A B of Fig. 1. Fig. 3 is a vertical section of the lower end of said case on the line C D of Fig. 1. Fig. 4E isaperspective View from the front and lower end ofthe lid-opening spring forming part of my invention.

In the drawings, 1 is the case-center of the case. Said case-center is provided with an interior centrally-directed flange 2, preferably having the shoulder 3 and adapted to receive and support a works-containing rim. (Not shown.) A centrally-directed interior flange t is also formed upon said case-center. At its bottom end said case has an arched housing or recess 5, open at the bottom and closed,

at the top and at each side and at each end. A shoulder or stop 6 is formed on one wall of said recess. Hinged to said case-center is a front lid 7. The lower end of said lid has formed thereon a knuckle 8, adapted to project into said recess 5 and adapted to bear against the lower edge of said stop 8, which knuckle is hinged in said recess by the pin 9, directed through the periphery of said casecenter and through the side walls of said recess and through said knuckle. Said knuckle has a shoulder 8 formed thereon, adapted when said lid is opened approximately at a right angle to said case-center to contact with said stop 6. Positioned within said casecenter, between said flanges, is a spring 10, approximately concentric with said case-center and extending, preferably, about half-Way around said case-center and within the same. Intermediate of the ends of said spring a corrugated flange 1O is formed upon one edge thereof, either of the corrugations of which is adapted for the passage of a suitable means, as a pin or screw 10, by which it may be secured to either said flange 2 or A. Said spring has formed thereon a slender tip 10, which is adapted to project through a segmental slot 6, formed in one side wall of said recess 5, and into a recess 6 formed in the contiguous side wall of said knuckle. hen said lid is closed, the tip 10 will be sprung to one side by said knuckle, and when the lid is released the tendency of the tip 10 to return to natural position will throw said lid open. If desired, the back wall 11 of said case may also be constructed as alid and hinged to the case center of the case by any other suitable style of hinge or preferably by the same style of -hinge as that herein described, except that the spring-operating means may be, if desired, omitted as to said back lid. My said hinge thus presents a smooth exterior surface and is protected internally by a substantially dustproof housing or recess.

My said invention is obviously Within its spirit and scope capable of some minor modifications, and I do not, therefore, desire to be limited in all respects to the exact construction shown. Said hinge or said hinge and spring may also within the scope and spirit of my invention be used for other cases, as in lockets.

Having described my invention, what I claim, and desire to secure by Letters Patent, is-- 1. A case comprising in combination a caseccnter having a centrally-directed flange and a recess formed therein, a lid having aknuckle formed thereon adapted to project into said recess, and a spring positioned within said case-center and provided with a tip adapted to extend through a slot formed in one side wall of said recess and further extending into a recess formed in the contiguous side of said knuckle.

2. A case comprising a case-center having an outwardlyopening recess or housing formed therein, a lid having a knuckle formed thereon adapted to extend into said recess, a pin extending through said case-center and through said recess and knuckle and adapted to form a hinge for said knuckle, a spring positioned within said case-center and provided with a tip extending through a slot formed in one wall of said recess and further extending into a recess formed in the contiguous wall of said knuckle.

3. A case comprising a ease-center having side walls of said recess and through said an outwardly opening recess or housing knuckle and adapted to form a hinge for said formed therein, said recess having a stop knuckle, substantially as described. formed upon one of its Walls, a lid having a In testimony whereof I hereunto aflix my 5 knuckle formed thereon adapted to extend signature in presence of two Witnesses.

into said recess, said knuckle having a shoul- LOUIS S. HANSON. der formed thereon adapted to engage said VIUDGSSBSI stop when said lid is open Wide, a pin extend- JAMES T. VVATSON,
